Salvaging maxtor/seagate SATA drives from their USB external counterparts

Posted by jpluimers on 2023/01/02

Interesting idea from [WayBack] Western Digital toont prototype van compacte externe 8TB-ssd – Computer – Nieuws – Tweakers:

Voor harde schijven moet je altijd bij de externe drives kijken, die zijn goedkoper (even open schroeven).

– 5 TB 2.5″ HDD: 0.018 EUR/GB
– 6 TB 3.5″ HDD: 0.017 EUR/GB
– 2 TB M.2 SSD 0.103 EUR/GB
– 1 TB 2.5″ SSD 0.096 EUR/GB

Grofweg zit er een factor 5x tussen. Probleem met SSD’s is vooral de schaling, de sweet spot qua prijs zit daar bij 1-2 TB, wat je niet veel helpt als je bijvoorbeeld 10 TB nodig hebt.

Dat is voor het eerst dat ik zie dat externe schijven goedkoper zijn… Hoe kan dat in hemelsnaam?

Losse harde schijven (vooral 2.5″, die dingen gaan in rack servers) gaan allemaal naar de enterprise markt, waar de klanten merkentrouw zijn en niet op een cent kijken. De concurrentie voor consumenten (externe) drives is daarentegen moordend.

Het is ook een soort ‘overschot markt’ voor de fabrikanten, loopt de HDD productie goed en is de enterprise markt niet heel hot, dan duwen ze wat extra goedkope externe drives de consumentenmarkt in en wordt het prijsverschil groter. Neemt de enterprise sector wel veel af of zijn er productieproblemen, dan verdwijnt het prijsverschil weer grotendeels.

Let wel: Western Digital soldeert de USB interface vast bij hun externe 2.5″ drives, Seagate/Maxtor doet dat (nog) niet.

Isotopp’s home sensor network

Posted by jpluimers on 2022/11/25

For my link archive an interesting blog post by isotopp (Kristian Köhntopp)

[Wayback] My home sensor network

I have been asked to document my home sensor network. Being married to a person with a background in web security sets boundary conditions:

  1. No cloud. We are running all services locally.
  2. No control, only metrics.

I am collecting data from a number of plugs with power meters over Wifi, using the MQTT protocol. I am also collecting data from a number of temperature sensors over Zigbee, and convert to MQTT. The MQTT data is ingested into Influx, and then read and plotted in Grafana. All of this is dockered and runs locally on an Ubuntu server.

I had some Windows ATOM issues before, but this beats them easily

Posted by jpluimers on 2022/10/19

I’ve had some issues with Windows ATOM tables filling up, but nothing like this security bypass:

A new Windows code injection technique, atombombing, which bypasses current security solutions.

Note that since writing the first draft, the above AtomBombing article moved via Wayback: blog.ensilo.com to [Wayback/Archive.is] AtomBombing – A Brand New Code Injection Technique for Windows | FortiGuard Labs.

LPRng: RESOURCES – PostScript, Epson, HP, Xerox, PPD, etc

Posted by jpluimers on 2022/09/28

When writing Some links on PostScript books and online content, back from the days, I archived [Wayback] Index of /RESOURCES from the site hosting the [Wayback/Archive.is] LPRng Web Page (see also LPRng on Wikipedia):

The LPRng software is an enhanced, extended, and portable implementation of the Berkeley LPR print spooler functionality. While providing the same interface and meeting RFC1179 requirements, the implementation is completely new and provides support for the following features: lightweight (no databases needed) lpr, lpc, and lprm programs; dynamic redirection of print queues; automatic job holding; highly verbose diagnostics; multiple printers serving a single queue; client programs do not need to run SUID root; greatly enhanced security checks; and a greatly improved permission and authorization mechanism.

The source software compiles and runs on a wide variety of UNIX systems, and is compatible with other print spoolers and network printers that use the LPR interface and meet RFC1179 requirements.

Subdirectories (the PPD one goes one level deeper with both files and directories; XEROX just has a subdirectory with one file):

Add AirPlay to Your Classic Stereo with an Old Apple TV – TidBITS

Posted by jpluimers on 2022/09/19

[Wayback/Archive.is] Add AirPlay to Your Classic Stereo with an Old Apple TV – TidBITS which has a good description including a list of needed parts:

  • Second- or third-generation Apple TV
  • Power cable
  • TOSLINK Digital-to-Analog (D/A) Converter
  • Pair of RCA Cables

These are only needed the first time to setup the Apple TV 2nd or 3rd generation:

  • HDMI Cable
  • Remote

Note that the Apple TV 4th generation or Apple TV 4K devices won’t work: they lack a TOSLINK interface.

You can work around this by using an HDMI audio extractor [Wayback/Archive.is]. Some can provide S/PDIF / TOSLINK output, others can directly do line out (so you do not need the above TOSLINK D/A converter):

Usually the Apple TV 2nd or 3rd generation solution is way cheaper, as they go for very little money on second hand sites.

Some links on Gigabyte GA-Z77-DS3H mainboards

Posted by jpluimers on 2022/09/05

The board supports mSATA which is an older standard so it is harder to get media for it. I keep mixing up mSATA and M.2 all the time, so:

The Gigabyte GA-Z77-DS3H manuals (see below) note “The mSATA connector conforms to SATA 3Gb/s standard and can connect to a single solid-state drive.”

Na migratie van XS4ALL naar KPN zijn al je telefoon-doorschakelingen weg: hoe dit te herstellen (spoiler: de on-line aanwijzingen kloppen niet)

Posted by jpluimers on 2022/09/02

In het kader van “kunnen dingen bij ons nooit eens normaal gaan?” het korte antwoord: nee.

Voorbeeld:

Voor de migratie van XS4ALL naar KPN hadden diverse telefoondoorschakelingen in gebruik (met name vertraagd doorschakelen: individuele nummers in ons huishouden gingen vertraagd door naar de bijbehorende mobiele nummers).

Na de migratie waren die allemaal weg. Het duurde even voor we daarachter waren omdat sinds de corona-periode vrijwel altijd iemand thuis is.

Kort en goed: we kamen er dus achter toen er niemand thuis was en we een opmerking kregen onbereikbaar te zijn (door iemand die ons mobiele nummer niet had).

Herstellen was ingewikkelder dan bedacht, want als je deze voor de hand liggende stappen van XS4ALL en KPN volgt kom je met een kluitje in het riet terecht:

Since about 5 months now, there has been a new Chocolatey package maintainer for OpenVPN

Posted by jpluimers on 2022/08/26

Last winter, I discovered that the OpenVPN version on Chocolatey was really old: it had not been updated since 2019.

Most  Chocolatey maintainers are volunteers and sometimes the burden can become too large. Back then the maintainer was [Wayback/Archive] Chocolatey Software | wget, but luckily [Wayback/Archive] Chocolatey Software | dgalbraith has stepped in and in March 2022 bumped the version from [Wayback/Archive] Chocolatey Software | OpenVPN 2.4.7 to [Wayback/Archive] Chocolatey Software | OpenVPN – Open Source SSL VPN Solution 2.5.4 and kept maintaining (currently there is [Wayback/Archive] Chocolatey Software | OpenVPN – Open Source SSL VPN Solution 2.5.7).
